I'm working with the Google Search Appliance and corresponding drupal module. I've followed the user guide linked on the project page (also here) on creating filters. I was hoping to create a date range filter, however, I'm a bit stumped on how to filter on content types that have date ranges themselves.
For example, if I had a content type of person who had a year range of 1900 - 1970 (IE, years they lived). I figured I would create a metadata field that would have each date listed, so that google would know each year the content type covers. The filter part is the part where I'm having trouble.
In my custom module, i'm trying to set my $query['gsa_query_params']['requiredfields'] to be a range of dates in the form of "1900|1901|1902". That does work, but if the range is too big (around 30 years), the search fails. I'm lost.
